SC77 Meter Reading Resistance Incorrectly

Hi all,

I have a Fieldpiece SC77 meter that I have been using for a couple of years. I noticed today that when set to measure resistance the meter shows between 0.5 and 0.8 ohms with the leads shorted together. I have tried some of my other leads and have the same issue. I mean I know 3/4 of an ohm is not a big thing, but I can put long leads on my meter, or little 5 inch ones and get the same reading.

Is this something I should be worried about? I am probably only worried because a month ago the k-type thermocouple mode was reading a few hundred degrees inside a 40 degree refrigerator. I tried 4 completely different thermocouples and a new battery and nothing changed. A couple of days later it is reading the proper temperatures again.

You know I would post your issue in the public TOOL forum. Both Travis and Russell with Fieldpiece frequent that forum and are more than happy to assist you with anything. Or Drop either or both with a message...Travid is "Ault51", and Russell is "RussellHarju".
They are great guys and probably just replace your meter if they deem it an issue for free...warranty or not, they really look out for us H-Talk guys.

As for the resistance compensation or internal zeroing...I find all my digital testing equipment does some erratic stuff when it is bitter cold or my batteries are giving up their last bit of breathe. I will usually take my DMM apart and clean the internal lead and thermocouple connections, they get gummed up with a film that causes some erratic readings...I do the same on my lead ends with a small round wire brush.
My K-Type thermocouples don't last long, for some reason the wire gets damaged internally, I don't know...It works fine one moment and jiggle the yellow wire and then it starts to fart out some whacked reading...so who knows. Digital instrumentation is a wonderful thing, but sure can get aggravating sometimes, and even plant seeds of doubt only at the times when you need a reliable partner.
